I always end up using the same spot effects, usually nabbed from the DKTronics SoundFX tape. I know we've got BeepFX for the more elaborate ones, but I thought this would be a good place to share shortish beeper routines people can use.

Wrote a complete beeper music player/sequencer in 64 byte earlier this year: url=https://github.com/utz82/ZX-Spectrum-1- ... /nanobeep2
In it's most basic setup, it has just two square wave channels, and 8-bit frequency resolution (approx. 2.5 octaves note range). The code is modular, so you can activate extra features like increased note range and PWM sweeps, at the cost of increasing the player size.

The player is open source and free for use by anyone, but there's no editor for the music available yet. There's a short demo tune included in the download package, if anybody is curious about how it sounds.

Ah cool, I wondered what happened to that site. I was just starting to learn the basics from scratch (the beeper, frequencies etc.) and then the site seemed to disappear - will have to get back to it..!

Here's a sound effect almost identical to the 'pick up object' sound I used in Catacombs of Balachor. It uses the ROM beeper, which I used at the time because I had no idea how to use OUT properly to make sound effects..!
